Abstract
Aim of the paper is to investigate the MHD effects on the unsteady boundary layer flow of an incompressible
micropolar fluid over a stretching sheet when the sheet is stretched in its own plane. The stretching velocity is
assumed to vary linearly with the distance along the sheet. Two equal and opposite forces are impulsively applied
along ? x axis so that the sheet is stretched, keeping the origin fixed in a micropolar fluid. The governing non-linear
equations and their associated boundary conditions are first cast into dimensionless form by a local non-similarity
transformation. The resulting equations are solved numerically using the Adams- Predictor Corrector method for the
whole transient from the initial state to final steady- state flow. Numerical results are obtained and a representative set
is diaplaced graphically to illustrate the influence of the various physical parameters on the velocity profiles,
microrotation profiles as well as the Skin friction coefficient for various values of the material parameter K. It is
found that there is a smooth transition from the small- time solution to the large- time solution. Results for the local
skin friction coefficient are presented in table as well as in graph.
